First lady Michelle Obama will attend the funeral to represent the president and also be one of the SXSW keynote speakers Wednesday.

In recent decades, presidents have not attended the funerals of former first ladies.

When first lady Betty Ford died in 2011, Rosalynn Carter, Michelle Obama, Hillary Clinton and Nancy Reagan all attended. Ex-President George W. Bush went because wife Laura had other travel plans. But Obama and former President Bill Clinton did not attend the funeral.
